Function: Return the first restart identified by IDENTIFIER. If IDENTIFIER is a symbol, then the innermost applicable restart with that name is returned. If IDENTIFIER is a restart, it is returned if it is currently active. Otherwise NIL is returned. If CONDITION is specified and not NIL, then only restarts associated with that condition (or with no condition) will be returned.

Function: Return the symbol named STRING in PACKAGE. If such a symbol is found then the second value is :INTERNAL, :EXTERNAL or :INHERITED to indicate how the symbol is accessible. If no symbol is found then both values are NIL.
